“…The main effect of the mixing height is the dilution of gases. 12 Since, in this work, the absolute values of CO emissions were also used as adjustable parameters, an error in the mixing height may be corrected by changing the emissions. The VOC/NO x /CO emission ratios were calculated in consistence with the vehicle emission inventory for the city of Rio de Janeiro and the FEEMA emission inventory for the Metropolitan Region of Rio de Janeiro.…”

Neste trabalho, dados de poluentes legislados e não legislados foram obtidos em uma região industrial-residencial no Rio de Janeiro, no período de abril a novembro de 2002. As concentrações de formaldeído e acetaldeído encontradas estavam na faixa de 25,25-231,73 ppb e 9,48-75,74 ppb respectivamente. Estas altas concentrações podem ser atribuídas a diversas fontes: emissões veiculares e industriais, a presença de incineradores de lixo, efluentes e rejeitos despejados no rio Faria Timbó e emissões de uma industria de metanol. As concentrações médias de BTEX foram: 1,92, 9,02, 6,37, 21,65 e 5,99 μg m -3 para benzeno, tolueno, etilbenzeno, m,p-xileno e o-xileno, respectivamente. As concentrações médias de PM 10 mostram valores máximos para o mês de outubro, abril e junho. As concentrações obtidas nas simulações foram para o mês de agosto usando um modelo de trajetórias. A concentração máxima de ozônio calculada foi de 39,8 ppb, as 15:00 horas, obtendo uma boa concordância com os dados experimentais (38,5 ppb). A isopleta de ozônio mostra que o local está em uma região alta de VOC/NO x , típica de áreas suburbanas e a favor do vento.In this work, data for criteria and non-criteria pollutants were obtained in a suburban industrial-residential area in Rio de Janeiro, from April to November 2002. Formaldehyde and acetaldehyde concentrations were found in the ranges 25.25-231.73 ppb and 9.48-75.74 ppb, respectively. These high concentrations may be attributed to several sources: vehicular and industrial emissions, the presence of several trash incinerators, effluents and waste rejected in the Faria Timbó river and emissions from a methanol industry. Average BTEX concentrations were: 1.92, 9.02, 6.37, 21.65 and 5.99 μg m -3 for benzene, toluene, ethylbenzene, m,p-xylene and o-xylene, respectively. PM 10 concentrations showed maximum mean values in October, April and June. Simulated concentrations were obtained for August 2002 using a trajectory model. The maximum calculated ozone concentration was 39.8 ppb, at 3:00 pm, in good agreement with experimental data (38.5 ppb). The ozone isopleths show that the local is in the high VOC/NO x region, typical of suburban and downwind areas.

This paper attempts to demonstrate the impact on tropospheric ozone according to VOC emissions from a landfill, located in the Rio de Janeiro Metropolitan Area (RJMA) at Niteroi city. It is well known that ozone is formed by the reactions of VOC, NOx and sunlight. The actual situation of this area is a low-medium ozone concentration due to high levels of NOx. The contribution of high VOC values from the landfill emissions will lead to a new situation with higher ozone values. The emissions of Morro do Céu Controlled Landfill (ACMC) (Niterói) were compiled together with meteorological data using OZIPR trajectory model coupled with SAPRC chemical mechanism. The input data for SAPRC were obtained using a VOC speciation by a representative sample collected at December, 2009 above the landfill soil. The samplings were done using evacuated electropolished canisters, and the chemical analyses were done by GC-MS following U.S.EPA TO-15 methodology. The base case used was adjusted for the RJMA using the annual emissions inventory done by INEA (Environmental Agency of Rio de Janeiro State) and the VOC speciation was performed at Rio de Janeiro downtown area. The ozone modeled for RJMA was compared with the ozone modeled for the landfill area, where the differences between the modeling procedures were the VOC speciation and hourly emissions. The results indicated an increase of 27% for ozone in the region of the landfill, indicating that the VOC emissions have to be considered.
